如何在二维数组中存储用户输入

本文关键字：存储 用户 输入 二维数组 | 更新日期: 2023-09-27 18:14:15

所以我有这个GUI应用程序，它应该计算运输成本。首先，我需要输入要运送的包的数量(已经完成)，然后从domainUpDown工具(也是完成的)中选择package #，然后在文本框中输入所选包的尺寸。这就是我被困的地方。这是我目前掌握的信息。

    const int WEIGHT = 0
    const int NMBR_OF_PROPETIES = 7;
    const int MAX_PACKAGES = 10;
    const double FLAT_RATE = 4.99;
    int numOfPackages, packageNumber;

    double[,] packagesArray = new double[MAX_PACKAGES, NMBR_OF_PROPETIES];
    public Form1()
    {
        InitializeComponent();
    }
    private void Form1_Load(object sender, EventArgs e)
    {
        //label texts get initialized
    }
    private void button1_Click(object sender, EventArgs e)
    {
        if (!int.TryParse(numOfPackagesTextBox.Text, out numOfPackages))
        {
            //message box tells that number cant be parsed
        }
        else if(numOfPackages > 0 && numOfPackages < 10)
        {
            //everything in the program is enabled       
        }
        else
        {
            //message box saying that you can't ship more than 10 packages
        }
        //adding package numbers to the domainUpDown tool
        DomainUpDown.DomainUpDownItemCollection items = packageUpDown.Items;
        for (int packageNumber = 1; packageNumber <= numOfPackages; packageNumber++)
        {
            items.Add(packageNumber);
        }
    }
    private void weightBox_TextChanged(object sender, EventArgs e)
    {
        packagesArray[(int)packageUpDown.SelectedItem, WEIGHT] = Convert.ToInt32(weightBox.Text); 
        //also here goes the rest of the dimension entry
    }//from here i don't know what to do, and im sure that this isn't right..

我感到困惑的是如何保存输入的文本，如果用户从domainUpDown工具以某种方式改变包号。

如何在二维数组中存储用户输入

您是否尝试过注册DomainUpDown的OnChanged或SelectedItemChanged事件?

在OnChanged事件处理程序上执行保存。

的例子:

     myDomainUpDown.OnChanged += new EventHandler(myDomainUpDown_OnChanged);
     void OnChanged(object sender, EventArgs e) 
      {
          //save all the information you need in whatever collection/file/db you want 
      }
